Exoplanet Atmosphere Breakthroughs

First atmosphere detected on rocky habitable-zone exoplanet LHS 1140 b via escaping helium. New Earth-sized habitable-zone planet HD 137010 b discovered 40 ly away (student discovery). GJ 3378 b and GJ 887 d added to prime targets. Zodiacal dust may hinder future studies. New: ESCAPE mission proposed to study stellar EUV/CME-driven atmospheric loss, 50x sensitivity, surveying 300 stars, key for habitability models.
